Hello,
here are commands how to compile u-boot for nokia n900, convert uboot image into n900 nand MTD file and run it under linaro arm version of qemu (upstream version of qemu have not merged n900 support yet):
$ export ARCH=arm $ export CROSS_COMPILE=arm-linux-gnueabi- $ make nokia_rx51_config $ make $ qflasher -x xloader-qemu.bin -s secondary-qemu.bin \ -k u-boot.bin -m rx51 -o u-boot.mtd $ qemu-system-arm -M n900 -mtdblock u-boot.mtd -serial /dev/tty
You need: * qflasher - Nokia generator of nand MTD image with CAL data * xloader-qemu.bin - Nokia first stage bootloader (X-Loader) * secondary-qemu.bin - Nokia second stage bootloader (NOLO) * qemu-system-arm - Linaro arm version of qemu
Linaro arm version of qemu can be downloaded e.g. from ubuntu: http://packages.ubuntu.com/source/precise/qemu-linaro (I'm using this version)
Nokia qflasher and bootloaders are proprietary and closed source but could be found on internet. License allows to redistribute binaries for non commercial purposes. If you are unable to find it on internet anymore (originally they were hosted on website repo.meego.com before intel turned it off) and you are OK with that license, I can send you needed files.

Hi Pali Rohár,
I am trying to reproduce the bug but I think I need the qflasher program for converting the u-boot.bin image into a qemu-compatible image. [1] [2]
Where can I get qflasher? Could you explain how to run Nokia RX-51 u-boot's image on qemu?
Thanks a lot,
Best regards,
Georges

Hello,
Nokia N900 board does not work anymore from master branch in qemu. I bisected first commit which broke it. It is:
41623c91b09a0c865fab41acdaff30f060f29ad6 arm: move exception handling out of start.S files
Before this commit uboot on n900 in qemu working fine. Since this commit qemu crash with fatal error (see below). I bisected other two commits which changed error behaviour, but still uboot is not working...
